The invention Vhas as a further `object to provide 9'.' thermostaticliquid controlling device particularly adapted to be used in abypass.

The invention has further objects which are more particularly pointedout in the accompanying description.

This application is a division of myl application Serial Number 271,314,illed May 2, 1939,

now PatentNo. 2,327,342 issued August 24, 1943.

Referring now tothe drawings, l Fig. l is a view showing one form ofdevicecmbodying the invention.

Fig. 2 is an` enlarged sectional view taken` on line II-lI.

Fig. 3 is a view showing the 'member for changing the area of thepassageway through the thermostatic housing.

Like numerals refer to like parts throughout the several gures.

Referring now to the drawings, there is illustrated a thermostaticliquid controlling device comprising a housing I0, havingan inlet '9.Within the housing I is a thermostat Il which controls a valve I2. This4valve is normally open but is closed when the temperature'in thehousing I0 rises to a predetermined point. This thermostat is a reverseacting thermostat. That isinstead of acting when the temperature risesto a predetermined poin't to open the valve, it acts when thetemperature rises to-a predetermined point to close the valve. Thehousing I0, which houses the thermostat l I, has a separable part'orsection il. This section preferably has a flange Il and the other partof the housing has a similar flange I5 and the two flanges are connectedtogether by the bolts or fastening devices it. The thermostat may be ofany design or kind and for the purposes of illustration, I have shown athermostat consisting of a coil of bimetal in a casing I1, which has aflange Il which is clamped between the flanges I4 and Il. The valve l2is pivoted in this casing at II.

Connected with one end of the housing Il is an inlet tube '2l whichdischarges into a passage- 4ifor different conditions1 and for enginesloi! diiferentsizes. For this purpose thereis provided a remoyableringll#which-ls fastened-'in position by the fastening devices 2l and 'islocated opposite the dischargev .end 1ofthe inlet tube 20. 'I'he inlettube 2l may also be varied as desired,

as 1t is removably connected m position in the housing, so that a tubeof 'any lsize or 'shape may Vbe used. -The 22 preferably has a curvedinner face 2l.

The housing M isprovided with a vmain outlet 24 at the end thereof. Thethermostatic housing l l has a second outlet 29 which is locatedpreferably opposite the inlet pipe, so' that'the inlet pipe 2|), whenthe valve |12 is open, will discharge the water past it into the housingI0. The device,

' when in use, ls connected up with the other parts a bypass which isnormally open and which has with which it is designed to operate.

The vuse and operation `of my invention are as follows:

When the device is connected with the pa with which it is used, theheated liquid enters' the inlet 9 andv it is discharged through theinlet pipe 20 and the inlet passageway 2| and through the thermostatichousing III. Since the vvalve l2 is normally open,'this liquid thenpasses out of the outlet 24 of the thermostatic housing to the pointdesired. The inlet' tube construction insures the water being moved pastthe outlet 29.

, When the liquid, passing through the thermo static housing |01,reaches a predetermined temperature. depending upon conditions present,the valve I2 closes and this causes the liquid to pass out of the secondoutlet 28 to be either discharged or conducted to any desired point.

:the valve I2 so that this liquid then passes out of the outlet" insteadof the outlet 29.

It will thus be seen that when this particular construction is used in abypass.' there is provided connect-ed with it an overflow dischargewhich is at all times open. It will further be seen that the inlet tubein conjunction with the ring 22, under normal operating conditions,substantially prevents the liquid from flowing through the continuouslyopen outlet 29 until the temperature of the liquid reaches apredetermined point. At this way 2| in the housing, and which ispreferably 5o point the theriostat closes the valve l2 and the Masamiheatedliquid passes out through the continuously size housing I0 for thethermostat and the valve for these different conditions. This isaccomplished by providing the means ioradjusting the passage between theinlet tube' andthe ring 22 as herein shown, wherein the ring 22 can. bemade of diiierent sizes and any one ot these sizes can be easily andquickly placed in the housing.

The inlet tube 20 may have a small opening 20a i1' desired, and whenthis opening is used, it provides a small circula-tion of liquid throughthe continuously open outlet 29.

I claim;

A thermostatic liquid controlling device comprising a casing having aninlet at one end thereof and an outletnear said inlet, a tube connectedwith said inlet and projecting into said casing and past said outlet,said casing having a second outlet member removably mounted at the otherend thereof, a valve for controlling said second outlet, a thermostat inthe 'casing` operatively connected with said valve and in the path ofthe liquid leaving said inlet tube, a restrictor annulus in the 2 turnoi.' uid past the tube until the valve has substantially closed thesecond outlet, and means connecting the valve and thermostat forinsertion, mounting and removal las a single unit in the casing inlongitudinal alignment with the inlet tubev and said second outletmember.v
